Planting techniques of Hot Pepper in greenhouse

Soil preparation and fertilization: apply base fertilizer based on organic fertilizer on the seedbed and dig trenches to make beds at the same time. | | Seedling transplanting: the chili seeds are germinated and sown in the seedbed, and then transplant when they grow to about 10 cm. | | Field management: pepper after transplanting should do a good job in the management of temperature, water and fertilizer and pest control.

When growing chili in greenhouse, you should pay attention to:

1. Planting time

Pepper can be divided into spring planting and autumn planting in the plain area. Spring-planted chili peppers are sown around January, which is the most suitable for growth. It can be sowed in late October at the earliest, covered with plastic film in the seedling stage for the winter, planted in February-March, and listed in April-May. Autumn is planted from July to August. In the mountainous areas of northern Guangdong, sowing can be arranged from January to early April according to the needs of the market. In addition, pepper can be cultivated out of season in winter in northern Guangdong.

If the region is different, the sowing time of hot pepper is also different. For example, in Hunan and Hubei in the south, the sowing time is generally in the middle of March of the lunar calendar. Most parts of the north are planted in mid-April (but must be indoors, waiting for the weather and temperature to average. The specific sowing time should be determined according to the local climate change.

two。 Appropriate amount of fertilizer should be applied.

In fact, the soil total salt concentration needed for the normal growth of hot pepper is 2000-3000 mg / kg, more than 6500 mg / kg root system will appear reverse osmosis and dry up, the yield will naturally decrease. The temperature and humidity in the greenhouse are high, the decomposition of organic fertilizer is fast, the utilization rate of phosphorus is 2-3 times higher than that in the open field, the volatilization of nitrogen is large, and excessive fertilization is easy to cause fertilizer damage.

3. Planting density should be reasonable

The plant type of pepper is compact and suitable for close planting. The experiment shows that close planting of pepper has great potential to increase yield, especially the green pepper which has been growing until autumn. Proper close planting is beneficial to early ridge closure, because the surface cover and shade, soil temperature and soil moisture change little, the root system will not be exposed after the rainstorm, which plays a role in promoting roots and seedlings.

Although the temperature, light and other conditions are better controlled in the greenhouse, the closed environment is also easy to cause the rapid spread of diseases. Therefore, it is very important to do a good job in pest control, and the majority of growers should pay attention to it.
